Spie Press Book

This Field Guide covers a broad spectrum of topics in the field of spectroscopy, condensing the subjects to their essentials. As such, novices can use this guide to obtain an overview of the field, and experts can use it as a quick reference. Beginning with basic definitions and explanations, this guide then describes the instruments that are used in the field-from filters, lenses, mirrors, and modulators, to monochromators, interferometers, and detectors. A third section outlines theory and methods as they relate to spectroscopy: the Fourier transform, quantum mechanics, approximation methods, nuclear magnetic resonance, and more. Additional features include a glossary of variables and symbols, and an equation summary.

Preface

Of all the Field Guides published to date, this one may stand out due to its relatively
broad topic: the field of spectroscopy. Indeed, entire field guides can be written on what
is covered here in one or two pages (witness the two pages on polarization here versus an
entire Field Guide devoted to that topic published previously). Whatever limitations this
may impart on this volume, I accept them and expect that the reader will understand them,
too.

This material is derived from several sources, including my own training in infrared and circular dichroism spectroscopy from Rice University and the Lawrence Berkeley Laboratory; from courses I have taught in spectroscopy at Cleveland State University; and from personal research I conducted in the course of authoring "The Baseline" column in Spectroscopy magazine since 1994. Writing is a form of self-education, and I have been blessed with fast (though not always accurate) typing skills with which I can benefit by increased writing and, as a result, learning.

Thanks go to my colleague, John F. Turner II, for his review of the initial Table of
Contents. I would also like to thank reviewers Brad Stone of San Diego State University
and Vidi Saptari of MKS Instruments, Inc., for their thoughtful comments on the manuscript,
and John E. Greivencamp of the University of Arizona, series editor, for leadership in the
Field Guides series.

This Field Guide is dedicated to my family: my wife, Gail, and my sons, Stuart and Casey.
